The type of microscope which would be the best tool to use to view the surface of a bacterial cell is a Scanning electron microscope.

This is because it can be used to look at the surface of objects at high resolution. Maximum magnification: Approximately 500,000x. Best for: Looking at surfaces of objects

<h3>What is a Microscope?</h3>

This refers to an optical instrument that is used for viewing very small objects and can be magnified several hundred times.

HELP WORTHA FREE BRAINLY IF RIGHT

zalisa [80]

Answer: The answers seem correct.

1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.

2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.

3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.

Describe the forms that water takes through out the water cycle

Aleks [24]

Gas: when the water has evaporated and is now out in the air. Water molecules move super fast during this stage.

Liquid: Water molecules have a good amount of space to move around, but they aren’t traveling as fast as they do in the gastric state.

Solid: ice in other words, the water molecules are super tight and compact, but are still moving around, just not very fast.
